--------------------------------------
Summary: Document how FileInputDStream works with object storage
Key: SPARK-20448
URL: https://issues.apache.org/jira/browse/SPARK-20448
Project: Spark
Issue Type: Documentation
Components: Documentation
Affects Versions: 2.1.0
Reporter: Steve Loughran
Priority: Minor
Object stores work differently from filesystems: intermediate writes not
visible, renames are really O(data) copies, not O(1) transactions.
This makes working with them as DStreams fundamentally different: you can write
straight into the destination.
1. Document how FileinputDStreams scan directories for changes
2. Document how object stores behave differently, and the implications
for users.
